I think it's definitely a "duh" that at least some news sources are deliberately misleading us. Propaganda and lobbying are rampant and always have been.

The poll is extremely ambiguous of whether it's talking about some or all or *most", etc. And even commenters here saying "duh" are also ambiguous about that.

> How can such people make educated choices?

Answering in a way that stays in context: by listening to trustworthy news sources. (I don't think this contradicts the poll.)
